Pip install doesn't recognize torch

In my current setup, when installing yolox, the installation process exits with an error:

pip install -v -e .
AssertionError: torch is required for pre-compiling ops, please install it first.

However, torch is installed in my environment, as returned by pip list:

torch 2.0.1+cu117
torchvision 0.15.2+cu117

I am working with the most recent version:
https://github.com/Megvii-BaseDetection/YOLOX/commit/d872c71bf63e1906ef7b7bb5a9d7a529c7a59e6a

My python version is:

python --version
Python 3.10.15

The full error message is:

Start by reproducing pip install -v -e . with Python 3.10.15, torch 2.0.1+cu117, and torchvision 0.15.2+cu117, then inspect the editable-install build configuration and its isolated environment. Done means the YOLOX editable installation completes without incorrectly reporting that torch is unavailable.
